Da schlug David unter sie von der Dämmerung bis zum Abend des folgenden Tages, es entkam kein Mann von ihnen außer vierhundert jungen Männern, die auf Kamelen ritten und geflohen waren.
Rashi
וישב ביום ההוא עשו לדרכו SO ESAU RETURNED THAT DAY ON HIS WAY — Esau alone returned, but the four hundred men who had accompanied him slipped away from him one by one. When did the Holy One, blessed be He, reward them for this? In the days of David, as it is said (1 Samuel 30:17) (in reference to an attack which he made upon the Amalekites, descendants of Esau) “[and there escaped not a man of them] save four hundred young men who rode upon camels” (Genesis Rabbah 78:15).
Rashi
For You light my lamp when he fought at night with the Amalekite troop that attacked Ziklag, as it is stated (in I Sam. 30:17): “And David smote them from evening until evening to their morrow.”
